API is failing while integrating the Metrick with Jenkins pipeline

[yugandharakulkarni-cg-devops]

Hi Team,

I have installed the Metrick and tried to connect with the Jenkins pipeline. When I have specified the URL of the pipeline it does not take. It is showing the error:
"jenkins.abc.com executing GET https://jenkins.abc.com/jenkins/job/OMS_Metrick/wfapi/."

As I have to debug this error. It is due that the GET method that Metrick is not taking it.
{"status":500,"message":"Request method 'GET' not supported"}

Please look into this issue. As i am trying for DevOps metrics.
